ENGR 233 question

I have my first engr 233 midterm coming up and I was just wondering if it is expected for students to know trig sub. I lowkey forgot it and already have so many things to catch up on and don’t really feel like wasting time relearning it if it’s not necessary for the class.

Any other information/advice on how to succeed in the class is more than welcome,

Also idk if it’s just me but it’s a lot of material to study for for just one midterm lmao
